AI Technical Summary
Existing hydraulic bollards are repeatedly run over by vehicles, causing mechanical parts to loosen and hydraulic components to fail prematurely, resulting in a shortened service life and increased maintenance costs.
The hydraulic bollard adopts a clutch-type design. Through the cooperation of the buffer mechanism and the pressure-bearing mechanism, the bollard is separated from the pressure-bearing mechanism, avoiding direct transmission of vehicle pressure. The pressure-bearing mechanism is lowered into the road surface by the buffer spring and the ring buffer base, reducing repeated rolling.
It extends the service life of hydraulic lifting columns, reduces maintenance costs, and improves the stability and durability of the equipment.
